Several species of Vigna and Bolichoa, not occurring in recent collections, are mentioned 

 by Macfadyen as cultivated in Jamaica : viz. F. unguiculata, Walp. (JJolichos, Jacq. Vind. 

 t. £3, 23); Dolichos sphterospermns, DC. (SI. t. 117); X). tuberosus. Lam. (Plnm. Ed. 

 Burm. t. 220. Desc. Fl. 8. t. 554); and 2). sesquijiedalu, L. (Jacq. Vind. t. 67). — B.fili- 

 formis, Macf. (non L.), is unknown to me, but from its " monadelphous stamens" is no 

 congener of either of these genera: by its "falcate legumes" and "ovate leaflets" it differs 

 from D.filiformis, L., which likewise is an unknown Jamaica plant, and has " linear leaflets, 

 the middle twice as long as the lateral ones :" both are to be compared with Teramnus.

Calyx campanulate, shortly 4-5-fid. Standard roundish, auricled at the base, bicaUous 

 in the middle. Stamens diadelphous. Style cartilaginous, usually compressed above, and 

 hairy : stigma terminal. Legume compressed : valves convex or flat : seeds separated by 

 thin, spurious dissepiments. — Leaflets 3, *ftj)e/toe ; inflorescence anllary, fascicled-race- 

 mose.

 4-fid, the upper lobe broader; keel beaked-falcate; style compressed; legume scimitar- 

 shaped, flat-convex, with an oblique, or recurved, straightish point : margins submuricate :

97. Ph. lunatus, L. Stem usually twining; leaflets ovate, pointed; peduncles shorter
